Jacinth-Ambrosia is the world’s largest zircon mine.
Jacinth-Ambrosia mining activities, which were idled in April 2016, were restarted in December 2017 as planned.
A definitive feasibility study is expected to be completed by mid-2018, with project execution expected to commence in the second half of 2018 and completion in 2019, subject to Board approval and market conditions. |

Summary:
Deposit:
-two contiguous deposits: Jacinth and Ambrosia;
-lenght 5 km; width 900 metres;
-free running fine grained sand;
-overburden 8 metre average;
-ore thickness range from 20 metres; average depth 45 metres;
-average strip ratio 0.5 to 1.
